March 12, 2018 -- Franklin Institute

.

On March 12, 2018, we visited the Franklin Institute -- a science/hands-on museum.

It was full of screaming children.  I can't understand why adults bring children to museums and then let them run wild.  No, no, no.  If you are going to let them run wild, take them to the playground.

Not into a museum, where you allow them to bash the exhibits just to see what noise it makes when you heavily crash scales into the surface below those scales.  For example.

No.



We tried to go only to places with no children.  We paid extra to see the IMAX presentation about the International Space Station.  No pictures allowed.............





Too, right, Bert, old buddy.  Keep asking.  Even when "they" don't like your questions.  (Like -- "why are these freaking children allowed to run wild in this space?!?!?")



Luckily I had ear plugs.  I used them.  This was part of an exhibit about technology and sports equipment.  There were actually some physically active things kids were SUPPOSED to do in that room.  The noise was ... too much.

But the information was good.  Bike helmets.  One crash = new helmet needed.



I can't remember what was in this space, other than these amazing images of neurons.....




This looks like yarn.  I would buy it.

And that was as much of the Franklin Institute as I could bear.

March 23, natural history museum, part 2

.

Dinocerata.  I like rhinos, so it's not a surprise that I would like this. 



Grateful to artists who have worked to help us imagine what these creatures were like......




Pigs.  Interesting how different the eye opening is, between these two skulls.



I know sheep horns can sometimes curl the wrong way and end up puncturing the skull.  Apparently boar tusks may be able to do that, too.  There was barely enough space between this tusk and the skull to accommodate skin.....



The museum has a lot of minerals.  Travertine.



Mammoths lived around here.  They were LARGE.  That green-circled text is at my eye level.



It seems to me that the "earliest date for fire-use by humans" keeps getting pushed back and back.  Apparently that date may be a million years ago.  Or more.

I think this is a really effective display, done low-tech.  The rocks and burnt sticks are real, and there is a photograph of flames behind them.  Pretty sure anyone who's ever seen a campfire would see this display as a campfire.....

We humans would not be who we are without the ability to produce fire at will.  Cooking allows us to make use of a lot more of the calories in our food.  Without those extra calories, we could not support the prodigious energy needs of our big brains.....



Speaking of fire, and of things within our control...........  Spotted this sign in the museum. 

Each of us has a choice.  We can just repeat things we've been told by someone else, or we can check just a bit and see if those words seem to actually be truthful...........




Thank you, Universities everywhere, for standing up for truth, facts, science, reality. 

Light in the darkness. 



Walking home.  Art on the sidewalk, by David Zinn.



Te right side of this guy's eye-glasses frame is something metal that was sawed off at sidewalk level.  An ex-parking-meter, maybe......  The rest of him is David's imagination.



In West Park.  Looking back east toward downtown (and campus).  The man on the path has two nice corgis with him.  We got to say hi to them.



Turning back west toward home.

March 23, natural history museum

.

Ceiling in the rotunda.  So glad they will preserve this building.


The Acasta gneiss is the oldest known exposed rock on Earth.  According to Wikipedia, the rock body is exposed on an island about 300 kilometres north of Yellowknife, Northwest Territories, Canada. The rock of the outcrop was metamorphosed 3.58 to 4.031 billion years ago and is the oldest known intact crustal fragment on Earth.[1]




Model of Trimerorhachis.  If I recall correctly, this guy was working on being a yard long.  I don't remember seeing this model before.


Above.  The model is above, not below.  :-)



This next model is someone else entirely.  The front of its top jaw comes down in a point, and the front of its bottom jaw comes up in two points which surround the top-jaw point.  The model of scaphonyx is about 15" long.



Pterodactyl.



Closer look.  That bone around (in?) the eye......




Ok-to-touch cast of the skeleton of a teeny tiny pterosaur.



Ok-to-touch life-size model of an allosaurus  head.  I should have touched this one, too, so you could see how big it is....



Closeup.

July 11

Downtown Des Moines.  A lot of it has a human scale and a pleasant aspect.




The science museum has a large building, with interesting spaces.




They introduce some of the interns at the museum.  (At least -- that's what I remember about who these people are.....)

I think these displays are fun, and I appreciate all of each person's different interests.  Ellie doesn't mention yoga, but it's something she knows about, too.




The thing I like best about Celeste's intro is her portrait with the dog.



Love this dog.............  Looking up into her/his jowls?  Cool.



The museum was oddly empty.  A huge space, but not that many exhibits.  And those that exist seem to be about inviting random behavior until success appears, rather than about learning how something works so one can consistently get it to work.  Odd.

They have several art pieces that were clearly quite costly.  I suppose if your donors want to give you art rather than science, you say "Thank you!" and hang up those donations, but it would be a more interesting science museum if it had more science.

At least they have lots of space to put science when they get more money to add it.



This was my favorite thing.  It's like a microscope, only it's video.  The embiggened image on the screen is one we're seeing through a camera's eye, as well as seeing it through lenses, rather than seeing the subject through the lenses directly with our own eyes as we would with a regular microscope.

It's really easy to use -- stick something under it, zoom as much as you like (to a point), then focus.  Those gold-colored slider things on the front of the vertical gray tube zoom and focus.) 

The white disks under the camera are slices of tree branches.



Tree slice, closeup.  I wonder what all the colored dots are.  Random specks of crayon?



Spider legs laminated to a piece of card stock.



As with any microscope, preparation of your subject makes a difference.  Lamination is not the best choice for preserving our "hairy" leg for viewing (note all the broken pieces at right....).



They have one of these, down where you can touch it.



The lit up plasma inside behaved quite differently, sometimes, when it was touched.  I couldn't feel anything, but my fingers on the glass clearly had an impact on the contents.



They had the same "nano" exhibit we saw in Reno, but the coolest thing (the nano particles of iron in water[?]) was not ... clean?  The particles were glopped together rather than behaving like a liquid, the way they did in Reno.

This is part of that exhibit, I believe.  It was stuck to the back wall of an elevator.  I did not know this.



They have a Foucault pendulum.  I'm guessing this is another quite expensive item that doesn't, in my humble, teach much science for as much as it cost.  It's pretty, with its pendulum swinging right over Iowa on every stroke, but an odd choice of expenditure, in my opinion.



I am coming to think the Reno science museum was brilliant to include that big interesting climbing structure.  Little kids, turned loose in any space, will sooner or later want something *active* to do.  (For many of them, they will always and only want active things to do, I think.......)

Putting in a play structure gives those kids somewhere to be where they are not banging mindlessly on the other exhibits.  This makes them happy, and makes people who are actually interested in the exhibits happy, too, because the exhibit areas are quieter and less crowded.

Our national Mall in Washington, DC, needs a huge playground.  Get those noisy bored kids out of the museums, and let them use up their energy (and make their noise) *outside*................ 

Please.



I think this was the evening we ate at Eatery A, which was interesting and tasty. I would eat there again, if I lived in Des Moines.
